Title: Improvements in or relating to liquid pressure servo-motor devices
IPC: B60T13/14
Filed: 1944-04-28
Abstract: 580,283. Fluid-pressure actuated brakes. AUTO MOTIVE PRODUCTS CO., Ltd., and CHOUINGS, L. C. April 28, 1944, No. 8035. [Class 103 (i)] [Also in Group XXIX] A fluid pressure servomotor particularly applicable to the hydraulic operation of vehicle brakes comprises a piston member 22 working in a cylinder 11 and having a bore 50 in which is carried a valve member 56 which controls the inlet of pressure fluid to, and the exhaust from, a working chamber 40 of the cylinder. The pressure fluid is supplied through a connection 35, an annular space 36 formed in the piston, and a passage 60 to a chamber 61 around the valve member from whence it is controlled by a valve head 55 through a central hole 57 in the valve member to passages 69, 70 and the working chamber 40. The exhaust from the chamber 40 is controlled by the other end 67 of the valve member 56 cooperating with a frustro-conical recess 68 in a spigot 49 of a sliding thrust member 42, the exhaust passing through a passage 66 in the piston into an annular chamber 24 and to an outlet connection 28. When the thrust member 42 is moved to the left by, for example, the brake pedal lever 45 of a vehicle the conical seating 68 closes on to the end 67 of the valve member to close the exhaust passage and lift the valve head 55 off its seating to admit pressure fluid to the chamber 40 to move the piston 22 to the left to "follow-up" the movement of the valve and thrust member 42. The pressure of the fluid in chamber 40 reacts on the thrust member 42 to give the operator the "feel" of the braking effort. On release of the pedal the inlet valve head 55 closes and the exhaust passage is opened to relieve the pressure in chamber 40 for the piston to return by pressure of a spring 78. As shown the cylinder 11 also constitutes the master cylinder of the vehicle braking system and fluid in the chamber 20 of the cylinder is put under pressure by movement of the piston to actuate the rear brakes 18, 19. The front brakes 71, 72 may be actuated direct from the pressure fluid supplied to chamber 40. In the event of the supply of pressure fluid failing the shoulder 52 of the thrust member abuts against the piston to move it normally and so operate the brakes.

Title: Improvements in the reduction of metal articles to desired sizes
IPC: C25F3/02
Filed: 1943-05-21
Abstract: 568,207. Sand-blast. MOND NICKEL CO., Ltd., and PFEIL, L. B. May 21, 1943, Nos. 8119/43 and 7483/44. [Class 60] [Also in Groups II, XXII and XXXVI] In a process for fabricating metal articles by reducing their size by anodic dissolution, in order to prevent undesirable pitting of, and to expose flows in, the metal surface, the dissolution process is interrupted at least once and the surface abraded by shot-blasting, sand-blasting, grinding. In this way, larger amounts may be removed than is usual in known anodicdissolution polishing processes, and the process may replace or precede the last machining stage, such as rolling or forging. For example, a turbine blade may be roughly forged to shape, then processed by the means according to the invention, then forged to final shape and reduced to exact size by the process of the invention. When there is more than one interruption, the period of treatment before each one are increased successively throughout the process. Shaped cathodes or anode-shields may be employed for removing amounts which vary at different parts of the surface. The Specification gives numerical figures for shotblasting, degree of concentration of hydrochloric acid, and temperature and current density of the bath. For treating an 80/20 nickelchromium alloy, the electrolyte of Specification 526,854, [Group XXXVI], may be employed, namely 55 per cent by volume concentrated H3PO4, 27 per cent concentrated H2SO4' 18 per cent water, one process being specifically described as an example. Pickling may be employed to loosen every adherent scale before shot-blasting. A 2/1 nickel-copper alloy also is referred to.

Title: Improved method of manufacturing combined sound and pictorial films
IPC: B63C11/22
Filed: 1935-03-15
Abstract: 450,029. Combined sound and picture films. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. March 15, 1935, No. 8148. Convention date, March 21, 1934. [Class 40 (ii)] An optically-reproducible sound-record is mechanically produced on a finished positive picture film by means of a recording tool vibrating substantially perpendicularly to the film surface, the width variations of the record being preferably a proportional enlargement of the amplitudes of movement of the tool. One method of carrying out the invention consists in providing a blackened strip on the film for the sound track, which strip has one or more ridges of triangular section. A tool 16, Fig. 9, having a straight cutting edge parallel to the film surface, engages the ridge or ridges 15 so as to produce a single track or a number of identical tracks, by removal of the blackening surface in known manner. The blackened strip may be obtained on the positive by photographic printing, using a negative with a transparent strip at the portion corresponding to the sound-track, or by colouring. Recording may be effected with a chisel having a slanting cutting edge, in which case it is desirable to use a " raw " positive film having two gelatine layers at least at the sound-track portion, only the upper layer containing photographic emulsion. A composite chisel 13, Fig. 7, may be used for recording simultaneously a number of identical shallow sound tracks; a second gelatine layer may then be dispensed with. The invention is particularly adaptable for " postsynchronization " or for re-recording, and may be used for the production of a number of sound and picture films simultaneously.

Filed: 1922-03-23
Abstract: 199,469. Freeborn, J. E. March 23, 1922. Chucks.-A self-centring chuck of the type having jaws consisting of eccentrically-mounted rings, has the latter uniformly disposed round the chuck axis and so coupled together that a rotary movement, imparted to one ring causes the others to rotate in the same direction and at the same speed, thus causing the opening formed by the entire group of rings to increase or diminish in size. The chuck body a, Fig. 3, carries eccentri. cally mounted rings a<3>, a<4>, &c. which grip an article by means of the medial opening t. The number of rings is greater than the number of points of grip required, to counteract the lateral thrust due to the jaws being in different planes. The rings are coupled together by links or pins, and one ring may be formed with worm-wheel teeth for rotation by a worm. The range of the chuck may be varied by the device shown in Fig. 5, in which a hollow sleeve e<1> is secured to one ring and carries studs f<1> which are engaged by inclined slots in a collar e<2>, slidably keyed to a hollow shaft e connected to the chuck casing. To vary the range, the pins are disengaged from their notches and re-engaged in others angularly displaced from the original ones. When used for gripping an article internally, the rings are mounted on eccentrics secured to a mandrel. In a modification, the article is gripped by small discs pivotally mounted between the rings. In a further modification, Fig. 17, the jaws a<5> are secured by lugs q in the rings m, and each of the latter is provided with three eccentrics n carried by studs n<1> which are rigidly attached to a plate rotated by bevel gearing to actuate the jaws.
